  • Few Camshaft Grinding/setup Questions

    I know a few people are using grinds the same as or similar to Jasons Isky grind.And as he posted the information card with all the specifications will i be able to take this information to the local camshaft specialist and have them reproduce this camgrind successfully? Its not so simple as getting a genuine Isky grind due to where i live and im not shipping cams halfway around the world for something that could be done here.On the other hand from reading an article of this forum (it was the old one which went into a bit of detail about the art of designing a cam) i gather that there is lot more to a cam grind that just duration and lift.

    After a previous topic on hitting 300whp on a stock t3 and considering the comments made i am looking for a healthy torquey 250 whp with street strip ported heads,performance 3 angle valve job,gutted plenum FMIC and a factory spec T3 turbo.(perhaps 8-11 psi) Would Jasons 270/262 grind be suitable for these mods or would a notch down perhaps be better ?I also understnad that to really utilise a cam grind adjustable cam gears and degreeing would be involved. Keep in mind running healthy advance is not an issue with how easy it is to get 98 octane gas/race gas
    plenty of power and torque from 3000 revs to 5500 revs would be great
    Car will not be a daily driver

    Did the NZ cars get the US cams or Australian cams standard? Just interested to know. Also, 98Ron is different to what they are talking about in America. I think 98 is equivelent to 92 in America. I run 12PSI with an FMIC, ported and polished heads, T3/T04b turbo with no sign of detonation (and thats at up to 40'C ambient temps).

      Im pretty sure we got JDM Cams My engine is Identical to a JDM engine with no EGR crap or what not on it.
      Are the AUS cams the same as JDM ones?

        no, i think the JDM are the same as US. Aus/euro got a different grind. The Aus motor has 10HP more. The info is on vg30et.com

        Is your car an NZ delivery or private import? Strange you have slicktops there.
